How Do Contact Lenses Work?
Contact lenses relaxation in your cornea atop a constant supply of tears. The contacts are also held in place by pressure exerted from the eyelids. While you blink the pressure from the eyelids cause the contacts to move slightly and glide over your cornea. This permits the tears underneath to softly flush out trash or particles that will have gathered in your eye.
This is just how the contact stays on the eye and is able to provide a way to appropriate vision. The way the vision is corrected is a different story altogether.
Contact lenses are prescribed to a wide variety of individuals who've vision problems related with astigmatism, nearsightedness, farsightedness, and presbyopia. The retinas of individuals that suffer from these conditions can not properly focus light. When the retina doesn't operate properly and/or doesn't properly focus light then the result is imperfect and blurry vision.
Contact lenses are made otherwise depending on the eye condition they're attempting to correct. For instance, when you endure from astigmatism your optometrist will measure your cornea so a contact may be made precisely to fit your eye. By doing this a contact is made that may fit your eye completely and direct light rays to one place on the cornea, which in flip corrects your vision.
These affected by myopia, also known as nearsightedness, will wear lenses that are thinner in the center and thicker on the edges. This design permits the light rays to be processed correctly by the retina.
Farsightedness victims are prescribed just the opposite contact lens, but with the identical finish result. They permit the retina to process light appropriately as well, resulting in corrected vision for the wearer.
All contact lenses use the essential technology to appropriate vision for the wearer. They redirect light to the retina so it is processed correctly. The only distinction is contacts are made otherwise to deal with completely different eye problems.
